(struct font_info): This definition is moved to

fontset.h.
(struct x_display_info): New members Xatom_PIXEL_SIZE,
Xatom_MULE_BASELINE_OFFSET, Xatom_RELATIVE_COMPOSE, and null_pixel.
(x_list_fonts, x_get_font_info, x_load_font, x_query_font):
Declare external.
(struct x_output): New members font_baseline and fontset.
(FRAME_FONTSET, FRAME_X_FONT_TABLE): New macros.
